SPRINGFIELD, ILLINOIS BRAKE-HANGER SUPPORT Y I Application led December 24, 1925. Serial No. 77,628.

My invention relates to means Jfor supporting the hangers whereby the brake beams are pendently held in place from the truck side frame. Truck side frames, as more generally employed at present, usually comprise a one piece structure made of cast or pressed steel and pro-vided with apertured brackets or lugs, adjacent to the vertical compression members of' the side frame, for the purpose of receiving a bolt or pin disposed through the apertured lug and through the eyes or openings in the brake hanger; the hanger being ot a U-shape link type adapted to straddle the lug on the side trame and held in place by the head o-IF the pin at one end and a'split pin or cotter at the other. This method is objectionable because of the frequent loss of the split pins or c-otters and the consequent dissociation of the members which wouldv permit the brake heads and shoes to drop.

My invention has for its robject the provision of a construction adapted to overcome these objections and which will permit of the substitution of a loop type of hanger, when desired, for the Uv-shape hangers and whereby the hangers wiil be securely held in place; the invention involving means which vmay be easily and readily put into place to maintain the hangers in proper position.

The objects and advantages ot' my invention will be more readily comprehended from the detailed description Lof vthe drawings, wherein y Figure 1 is a side elevatio-n of a truck side frame provided with one form of my hanger Vsupporting means; the truck springs, brake beams and other elements being omitted.

Brake hangers have heretofore generally vbeen suspended in place from aperturedlugs,

Vor eyes, through which a headed pin orvbolt passes; the pin also passing through the aperture in the side framed lug, with the L J-shape hanger straddling vthe lug; the pin being held in place by means of asplit pin or Cotter.

My invention consists in providing the inwardly disposed bracket armor lug 15` (generally formed integraliwith the truck side` frame at a point adjacent to the vertical Vcompression members 16) Lwith a transverse slot at the outer end of the lug 15,'thereby providing 4 the lug witha bii'urcated end` consistingof the upper and lower portions A17 and18 integrally connected at a point rearward of the hanger or pin receiving socket as shown yat 19. The lower portion 18 is provided vvith a Y socket at 20, which, in the construction shown in the yfirst three figures of the drawings, is intended to receive one end of a link hanger 21 which isin the nature of a continuous loop as shown; the link or hanger beingheld free to yhave oscillatory.movements in the socket portion 20g Theends or bifurcations and 4at their forward or outer ends are spaced apart sufficiently to not only permit passage of the link therebetween but to also receive a keeper plate or retaining member 22 which is preferably of width corresponding with the width of the bifurcations or ends 17 and 18 as Vshown-in Figure2. The inner end of the keeper plate or member 22 on its lower sideis preferably dished as shown at 23 to fit over the upper end' of the hanger 21 and permit the latter to have the swinging movement necessary. The slot is so formed that the inner or connected side 19 preferably is' provided with a shoulder 24 to receive ythe retaining member 22, see Figure 3,,thereby duced inner end ofthe keeper plate or reproper place, is adapted to register with similar apertures in the bifurcations 17 and 18 for the passage of a bolt or pin 26' provided with ahead27 which restsfon the upper face of the bifurcation 17, while the lower end of the -pin preferably, extends through the bifurcation 18 and is shown apertured at 28 to receive :a-cotter or split-pin shown at 29 in Figure 1.

The bolt or pin 26 is thus vheld against displacement; although it is apparent that the pin 26 will be held in place by gravity 1n the 'event of'displac'ement of the split'keyor cotter 29. i Y

In rFigures 5 to 10,1 show the brake hanger in the nature of aU-shape link 30, shown in detail in Figure 10, the upper ends whereof are apertured as shown'at 81 for the passage of a pin or bolt 82.

The side frame, like in Figure 1, is provided with the bracket arm or lug 15, having the transversely slotted end which provides the top and bottom bifurcations 17 and 18; with `Vl451 eted at 2O to receive., the suspending bolt or the bottom portion suitably dished or sockpin 32"; one end whereof is usually provided Ywith* a hea-das shown at 83. i o With this construction the eyes or aperturedlends of the U-shaped link 30 extend above the horizontal plane of the bolt or pin 32, as shown in dotted lines in Figure 6 and l infull .lines inl Figure 5. The keeper plate or-reta-ining member 34;, which enters the slot betwen the bifurcations 17 and 18 of the y bracket arm,-is shown of length greater Athan the width of the ends 17 and 18, see Figures [V5 ',andf7 ,v and'- therefore is provided with the cut-out portions or slots85'. 85 for the pas- V[sage of the a-pertured ends of the suspending `link 80. 1

f Thekeeper plate or retaining member 811 Y' at its inner end, like the keeper plate 22, isV

reduced to fit overthe pin or bolt 82 and the "rear endVl 'of the keeper plate restsl on the shown in Figures 5 and 9.

TWith this type of keeper plate it is ap- Y parent that the pin or bolt cannot move longitudinally out of place and the use of a Cotter-pin is obviated.

The keeper' plate 34, like keeper plate 22 is'aeld in place by means of the pin 26 which passes through registering apertures in the portions 17 and 18 and the outer end of the plate 34.

The type of hanger shown in Figure 10 is the one at present generally employed and which is now held in place by a bolt or pin passing throughfthe apertured lug on the side frame, while the pin or bolt is held in place by a Cotter-pin, which soon corrodes and breaks and is often lost, with the result that the link holding pin or bolt works out of plate and the brake mechanism is allowed to drop and cause serious accidents or delays.

With the supportingslugs or brackets as at present formed on the truck side frames,

the use of the loop or link type of hanger r.;-

shown in the first three figures of the drawings is impossible; a type of hanger which is greatly desired by the railroads because it providesa greater bearing surface entirely across the frame lug and therefore a more secure and lasting constructionthan is the case with the U-shaped hanger and suspending bolt now employed, where the wear is confined to the eyes of the hanger and principally to the ends of the bolt. A

Vith my invention, interchange of the hangers may be quickly made by providing the ends of the lugs on the side frame with a transverse slot intersecting or extending from the outer end to the bolt receiving aperture therein as shown in the drawings, namely a slot adapted to receive the keeper plate 84 (i'fthe 'U-shape type ofhangerv SOis still to be employed) or the keeper plate 22where the loop or link type of substituted.
